I have achy dull chest pain every once in a while lasting usually about 5 minutes if that. Exercise does not worsen itpacs &pvcs at times; EKG normal.?

Atypical chest pain. Your pain is not anginal in character so it is not likely to be do to coronary artery disease. The underlying cause of your extra heartbeats should be clarified by a careful listening for a heart murmur, check of your blood pressure, careful taking of your history, and perhaps an echocardiogram. Your esophagus could be another source of pain (inflammation or reflux of stomach acid).
